General com-
ments regarding
multiple MPP
trackers In the case of inverters with multiple MPP trackers, there are two independent PV inputs
(MPP trackers) available. These can be connected to a different number of modules.
When using for the first time, set up MPP TRACKER according to the respective config-
uration (also possible later in the menu area "Devices and system components" under
the menu item "Inverter").

IMPORTANT!
The maximum current load of a single ter-
minal is 25 A. PV connection strings with a
total current (I
dcmax
) of more than 25 A
must be split between both PV inputs
upstream of the terminals (≤ 48.75 A).
Splitting the current by bridging from PV 1
to PV 2 at the terminal is not permitted.
